Description
Technical field
The invention belongs to technical field of lubricating oil, specifically, being related to a kind of Biodegradable lubricant oil and its preparation side
Method.
Background technique
Lubricating oil such as plays antiwear and antifriction, cooling in equipment operation and improves efficiency at the indispensable key effect, but
It is usually poor with the compatibility of environment.The biological degradability of conventional mineral lubricating oil is poor, if in production, storage and transportation and use process
Middle generation leakage just pollutes the environment.Since mineral lubricating oil biological degradability is poor, in addition enhancing and the state of people's environmental consciousness
Family environmental regulation it is stringent, the research and development of Biodegradable lubricant oil is increasingly valued by people.China market is most
Popular lubricating oil oil product is oily lubricating oil based on petroleum mostly, it is difficult to degrade, stay for a long time in the environment.The annual whole world disappears
Consume lubricating oil be ten thousand tons of 3600-4000, wherein 10,000,000 tons or so of lubricating oil due to leakage, splashing, oil gas evaporation, be packed for
The residual of product such as undeservedly abandons at the ecological environment that reasons are directly entered human living, serious contaminated soil and the water resource, destroys
Ecological environment.Currently, Biodegradable lubricant oil has become the important component part of Green Chemistry and green engineering field.
Biodegradable lubricant oil refers to the requirement for being not only able to satisfy mechanical equipment, but also can be micro- by activity in a short time
Biological decomposition is the lubricating oil of carbon dioxide and water, it is typically incorporated into the column of environmental friendly lubricant.Environmental friendly lubricant
Performance not only include biodegradability, but also the eco-toxicity including lubricant.Biological degradability and eco-toxicity are
Two different aspects, some noxious materials are also biodegradable, and non-toxic substance is generated after degradation；After some mass degradations
Product has stronger toxicity than original matter.Environmental friendly lubricant should ask biological degradability to get well, but require eco-toxicity and
Cumulative toxicity wants small.
Before earliest biological lubricant can trace back to millennium, people oneself started with animal tallow and vegetable oil
Lubricate the movement of object.The attention that ancient Egyptian lubricates wheel hub is made so that they start to lubricate olive oil calcium soap
With generation interest.Biological lubricant is properly termed as biology base environment-protective lubricant oil again, refers to being partly or fully originate from biological money
The lubricating oil of source or renewable agricultural or forest resourceies.Biological lubricant in addition to the characteristic with mineral lubricating oil, also as its
The advantages that raw material is renewable, biodegradable, small toxic action is concerned.Difference according to base oil divides lubricating oil
Class can be divided into three categories, mineral oil, synthetic oil and crude vegetal.The lubricating oil of plant oil base is a kind of environmental-friendly
Lubricating oil, such as soya-bean oil, corn oil, rapeseed oil, cottonseed oil, wherein enter market earliest is the profit that Germany is synthesized with rapeseed oil
Lubricating oil；Though crude vegetal can be directly used as lubricating oil because its oxidation stability is too poor so that its application very by
Limit.Synthetic lubricant fluid mainly includes synthesis hydrocarbon, synthetic ester, polyethers etc..Wherein the research of synthesizing ester oil is the most extensive.It shows according to investigations
Show, in Lube Oil In The World application market, the ratio of mineral oil is up to 85% or so, and vegetable oil accounts for about 2%, and remaining is synthesis
Oil.
